Subject: intel/fs: Use TEX_LOGICAL whenever implicit lod is supported
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ef0339d5ea645390dd2ab8b6c328311fc945025a;p=mesa.git

intel/fs: Use TEX_LOGICAL whenever implicit lod is supported

Make sure we include compute shaders that have a derivative group
defined.
